- Normally use '()' to deference. This has extra safety and issues a
fatal error if the underlying pointer is not valid.
However, in some cases we are happy with getting a null reference.
The refOrNull() method returns the reference without any checking.
Usage example:
autoPtr<OFstream> osPtr;
if (Pstream::master())
{
osPtr.reset(new OFstream(...));
}
writeViaMaster(osPtr.refOrNull());
- The writeViaMaster() call takes an OFstream reference,
but this is only used directly on the master.
The slaves will pass things through to the master.
- Some commonly used write methods that are independent of
the calling context (ie, 2D/3D data, geometry, fields)
- Provide singleton null() for ensightFile, ensightGeoFile.
Can be used for MPI slaves that need a file reference for their
methods, but will never write to it, but it is also reasonable
to use an autoPtr with rawRef() for that as well.
to ensure 'patchType' is set as specified.
Required substantial change to the organization of the reading of the
'value' entry requiring careful testing and there may be some residual
issues remaining. Please report any problems with the reading and
initialization of patch fields.
Resolves bug-report http://bugs.openfoam.org/view.php?id=2266
e.g. for the cavity tutorial the moving wall patch can be specified in
terms of the block vertices as before:
boundary
(
movingWall
{
type wall;
faces
(
(3 7 6 2)
);
}
.
.
.
or the new specification of the face as block 0, block face 3:
boundary
(
movingWall
{
type wall;
faces
(
(0 3)
);
}
Renamed the original 'laminar' model to 'Stokes' to indicate it is a
linear stress model supporting both Newtonian and non-Newtonian
viscosity.
This general framework will support linear, non-linear, visco-elastic
etc. laminar transport models.
For backward compatibility the 'Stokes' laminar stress model can be
selected either the original 'laminar' 'simulationType'
specification in turbulenceProperties:
simulationType laminar;
or using the new more general 'laminarModel' specification:
simulationType laminar;
laminar
{
laminarModel Stokes;
}
which allows other laminar stress models to be selected.
Individual inward-pointing faces are checked and if all faces are
inward-pointing the block is inside-out. These errors are fatal and the
message indicates which block the error occurs in and where in the
blockMeshDict the block is defined.
- bugfix (empty patches), and added detection of steady-state
scheme.
Caveat: when called via execFlowFunctionObjects will always produce a
zero field, since the oldTime field is not available for this mode.
Extrapolate internal field to walls for post-processing.
Uses as new syntax for handling the naming of multiple fields.
The input fields are selected via a wordReList.
For example,
fields (U "(T|k|epsilon|omega)");
The names of the resulting output fields use placeholder tokens for
flexibility. For example,
result zeroGradient(@@);
The '@@' placeholder is replaced by the name of the input field.
Eg,
fields (U T);
result zeroGradient(@@);
-> zeroGradient(U), zeroGradient(T)
Or,
fields (U T);
result @@nearWall;
-> UnearWall, TnearWall
NOTE:
The function object will skip over fields that only have
processor, empty, zeroGradient patches. The operation does not
make much sense for these, and it avoids inadvertently
re-processing fields twice.
- implemented using magSqr() instead of sqr().
For scalar fields they are the same, but can be useful
if this function object is extended for more field types.
